A full factorial experiment with four factors run by a golf enthusiast. The objective of the experiments was for the golfer to maximize her driving distance at a specific tee off location on her local golf course. The golfer considered the following factors:
T
= Tee height (cm)
H
= Holes the golf ball had been played for prior to the experimental tee shot
C
= Club type
D
= Time of day (on the 24 hour clock)
The data are in standard order, however the actual experiments were run in random order.
Coded values for A
, B
, C
, and D
should be used in the linear
regression model analysis, with -1
representing the low value and +1
the
high value.
data(golf)
A data.frame containing 16 observations of 4 variables (A, B, C, D, with y as a response variable.)
